« Discover an underwater world! The app offers a colourful and super interactive environment where the user can create and explore his own ocean. Assemble a ship (or a submarine) via a puzzle, while learning the name of each part of it. Once the puzzle is done, everything becomes interactive and it’s possible to manipulate the environment. The app helped me out when I had problems. It wasn’t perfectly interactive, but I thought that for the price, it was a great quality and very fun app. »
